This invention relates to improVements in dirigbles, the generati object of the invention being to provide the dirigible with a tubnlar member whic'h passes through the longitudinal centor thereof with its ends open, so

that air con pass through the tubular member, with engines located in the tubular member for forcing the air therethrough. Thus the dirigible is greatly strengthened by the w tubular member and danger of the body breaking apartis eliminated, and as there are no exterior parts connected with the body except the cabin, the resistance offred by the Wind 1110 the passage of the dirigible is re- 115 duced to a. minimum so that the speed of the ship is greatly increased and the ship can be driven with the minimum amount of power.

Another object of the invention is to provide means fo1 facilita.ting the inspecti0n of no the engines and the parts connected therewith by providing doors in the; tubular member, With a Walk for enabling attendants to reach the doors and inspect the engines by opening the doors.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically F pointed out in the appended olams.

In describing the invention in detail, reference will be had to che aocompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:-

tra 9 is a. sectional view through the In these views, the numeral 1 indcates the body of the ship which is formed in the usual or any desired manner and the numeral 2 in dicates a tubular member extending through the longitudinal center of the body, with ics ends openng out through the ends of the body. The front end of the tubular membr s of flaring formation, as shown at 3, so that a largo amount of air can enter the t1ibular member through this flaring portion. Struts 4: are placed be'bween the tubular member and the oute1 she1l.

A plurality of engines 5 is placed in the tubular mernber and a propellr 6 is fastened to the shaft 0' each engine, and is arranged at the front end of the ongine. Ah annular fuel tank 7 surrounds a part of the tubula,r

member a.nd pipes 8 connect the tank With the carbureters of tho eng"ines.

Sliding doors 9 are. arrlanged 1130 over openings in the "tubular member, each opening being located adjacent an engine, so that by opening the doors, the engines and the Pants attached thereto can be inspected or repaiied. A walk 10 extends along the door carrying side of the tubular member to enable attendants to reach thedoors.

The rear end of the ship is formed with the usual fins 11 and, of course, 1this end of the ship carries the rudders which are not shown.

'lhe gas bags are placed in the shell in the usual or any dosired mannor.

The cabin is shown at 12.

From the foregoing it Will be seen that the tubular member forms a central boro throngh Which air is orced by the motor driven propellers and the momentum of the ship, this tubular member acting ho greatly strengthen the ship and preventing it from breaking apart.

It is thought from the foregoing description that the advantages and novel features of the invention will be readil apparent.

It is to be understood thatc anges may be made in the constru,ction and in the combination and arrangement of the several pants, provided thai: such cbanges fall wthin the scope of the appended claims.

Wha.t I claim is r 1. A dirigiblo of the class described having S. tubular member arranged at the longitudinal center thereof, with its ends opening out through the ends of the dirigible, motor drven propellers in :the tubular member, the front end of the tubular member fiaring outwardly, an annular fuel tank surrounding a part of the, tubular member and pipes leading from the tank to the motors.

2. A. dirigible of the class described havng m a. tubul&r member arranged at the longitudinaml center thereof, With its ends opening out through the ends of the dirigible, motor driven propellers in che tubular member, the front end of the tubular member flaring out- 15 wardly, openngs in one side of the tubular member opposite the motors, doors for clesing the openngs and a walk along the (1001 carrying side of the tubular member.

In testimony whereof I aflx my signature. w CARLOS BARBERA.
